  2. Kinetic theory of gases - Wikipedia

    en.wikipedia.org/wiki/Kinetic_theory_of_gases

    The kinetic theory of gases is a simple classical model of ... While theories relaxing the assumptions that the gas particles occupy negligible volume and that ...

  3. Ideal gas law - Wikipedia

    en.wikipedia.org/wiki/Ideal_gas_law

    According to the assumptions of the kinetic theory of ideal gases, one can consider that there are no intermolecular attractions between the molecules, or atoms, of an ideal gas. In other words, its potential energy is zero. Hence, all the energy possessed by the gas is the kinetic energy of the molecules, or atoms, of the gas.

  4. Molecular chaos - Wikipedia

    en.wikipedia.org/wiki/Molecular_chaos

    In the kinetic theory of gases in physics, the molecular chaos hypothesis (also called Stosszahlansatz in the writings of Paul and Tatiana Ehrenfest [1] [2]) is the assumption that the velocities of colliding particles are uncorrelated, and independent of position.

  5. Gas - Wikipedia

    en.wikipedia.org/wiki/Gas

    Kinetic theory provides insight into the macroscopic properties of gases by considering their molecular composition and motion. Starting with the definitions of momentum and kinetic energy , [ 18 ] one can use the conservation of momentum and geometric relationships of a cube to relate macroscopic system properties of temperature and pressure ...

  6. Dumas method of molecular weight determination - Wikipedia

    en.wikipedia.org/wiki/Dumas_method_of_molecular...

    Two major assumptions are used in this method: The compound vapor behaves as an ideal gas (follows all 5 postulates of the kinetic theory of gases); Either the volume of the vessel does not vary significantly between room temperature and the working temperature, or the volume of the vessel may be accurately determined at the working temperature

  7. Ideal gas - Wikipedia

    en.wikipedia.org/wiki/Ideal_gas

    The ideal gas model has been explored in both the Newtonian dynamics (as in "kinetic theory") and in quantum mechanics (as a "gas in a box"). The ideal gas model has also been used to model the behavior of electrons in a metal (in the Drude model and the free electron model), and it is one of the most important models in statistical mechanics.

  8. Kinetic theory - Wikipedia

    en.wikipedia.org/wiki/Kinetic_theory

    Kinetic theory may refer to: Kinetic theory of matter: A general account of the properties of matter, including solids liquids and gases, based around the idea that heat or temperature is a manifestation of atoms and molecules in constant agitation. Kinetic theory of gases, an account of gas properties in terms of motion and interaction of ...

  9. Gas kinetics - Wikipedia

    en.wikipedia.org/wiki/Gas_kinetics

    At the molecular level, gas dynamics is a study of the kinetic theory of gases, often leading to the study of gas diffusion, statistical mechanics, chemical thermodynamics and non-equilibrium thermodynamics. [2] Gas dynamics is synonymous with aerodynamics when the gas field is air and the subject of study is flight.
